<![CDATA[ChangeDisplaySettings VC++ Linker-Error]]>Huhu 😉
Kämpfe gerade mit folgendem Problem:
Der untere Quelltext wirft mir in VC++ ständig Linker-Errors aus.

#include "stdafx.h"
#include "windows.h"

using namespace System;

int main(array<System::String ^> ^args)
{
int w=1024;
int h=768;
int d=32;
DEVMODE sDevMode;
ZeroMemory(&sDevMode, sizeof(DEVMODE));
sDevMode.dmSize = sizeof(DEVMODE);
sDevMode.dmPelsWidth = w;
sDevMode.dmFields |= DM_PELSWIDTH;
sDevMode.dmPelsHeight = h;
sDevMode.dmFields |= DM_PELSHEIGHT;
sDevMode.dmBitsPerPel = d;
sDevMode.dmFields |= DM_BITSPERPEL;
LONG rVal = ChangeDisplaySettings(&sDevMode, CDS_UPDATEREGISTRY);
    return 0;
}

Errors:

1>Linking...
1>new.obj : error LNK2028: unresolved token (0A000011) "extern "C" long __stdcall ChangeDisplaySettingsW(struct _devicemodeW *,unsigned long)" (?ChangeDisplaySettingsW@@$$J18YGJPAU_devicemodeW@@K@Z) referenced in function "int __clrcall main(cli::array<class System::String ^ >^)" (?main@@$$HYMHP$01AP$AAVString@System@@@Z)

In Dev-Cpp hingegen läuft der Code einwandfrei...
Weiss jemand wo der Fehler liegt bzw. wieso der Linker hier rumnervt?
